                                 Staff Report

                               November 30, 1979

                      Evaluation of the Halem Industries
                      "Pass Master" Device In Accordance
                         with Section 2222, Title 13
                     of the California Administrative Code


      Halem Industries, 414 Highpoint Drive, Cocoa, Florida 32922 has

      applied for an exemption from Section 27156 of the California

      Vehicle Code for the "Pass Master" device.       The applicant intends

      to market the device for 1979 and older model year gasoline powered

      internal combustion engines and some diesels.

II.   System Description and Function

      The purpose of the device is to turn off the vehicle air conditioner

      compressor during engine power demand periods such as acceleration

      or climbing hills.     It consists of a manifold vacuum switch which

      monitors engine vacuum drop during power demand periods and interrupts

      the voltage to the air copditioner compressor clutch during this

      period.   This idles the compressor and permits the 5 to 15 horse—

      power compressor drag to be used to move the vehicle.

III. System Evaluation

     The applicant submitted tests performed by the U.S. Energy

     Research and Development Administration.

     Pertinent excerpts from this report are as follows :

     The agency also performed emission tests on the same vehicle.

     Only the hot transient and the stabilizing phase of the CVS 75

     tests were used.

      The applicant also submitted tests performed at the Auto Club

      of Southern California in Los Angeles.      Pertinent excerpts are

      as follows:

IV.   System Evaluation

      Based on the submitted data, the staff is of the opinion that

      the device does not violate the prohibitions in California

      Vehicle Code Section 27156.     There is also some fuel economy

      benefit, which is to be expected; and, therefore the applicant‘s

      claim of improved mileage is valid.


      Based on the test data and submitted information, the staff is of

      the opinion that the "Pass Master" device should be exempt from the

      prohibitions in Section 27156 of the California Vehicle Code.        The

      staff therefore recommends adoption of Executive Order D—96.
